Vacuole

Vacuole

A vacuole is a small structural element of a cell that fills most of the cytoplasm or even occupies it entirely. Vacuoles are found in almost all eukaryotic cells. Most vacuoles contain a storage substance of the cell - parenchyma. It is this structure that is used by cells to exchange various substances between themselves and the extracellular environment.

**Vacuoles have another feature - the ability to stretch.** Their size can vary greatly, from small to gigantic. They contain a nucleus connected to the cytoskeleton, as well as organelles such as chloroplasts in plants, smooth muscles and ribosomes.

Bacterial vacuole.

A vacuole is a bacterial cellular organelle, which is a round or oval-shaped cavity bounded by a membrane. Bacterial vacuoles have different structures and functions. They are involved in metabolism and distribution of metabolic products between cells
